We successfully got 10 butterflies! My kids loved watching the entire process and later releasing our butterflies into the wild. Super easy and fun!!

This is great! We have done this several times and this time we had 9/10 caterpillars become butterflies! My daughter and our neighbors loved letting them out when they were ready to fly! What a great way to get more beautiful pollinators out in our world!

I’ve ordered caterpillars from insect lore for probably 5-6 years now. We always have a great experience. My girls love releasing the butterflies because they hang out with them for a while before flying off!

My daughter's and I have done this 3 years in a row so it's become a sort of Spring tradition. We look forward to watching the caterpillars turn into chrysalides and finally emerging as butterflies.

This was a really wonderful

This was a really wonderful experience. We loved and were amazed at every stage. We couldn’t believe how fast their bodies completely changed. It was really incredible.

I've purchased from Insect Lore

I've purchased from Insect Lore many times in the past, using the caterpillars as a fun activity for my preschool class. I no longer teach but I buy them now for my grandkids. They are so engaged and excited watching the transformation and ultimately releasing the butterflies. We had 10 caterpillars, with only 9 emerging this year. My granddaughter was upset but it made a good learning experience. Not everything in nature survives. I'll continue to buy as long as the kids are interested. I've been very happy with your company.

Our caterpillars were healthy and I think all them made it to the chrysalis stage, and all but one emerged.

For about 8 years, I

For about 8 years, I have been purchasing your caterpillars for my grandkids- now age 12 & 14. The 12 year old girl really takes care of them. Just last week we had our annual release event. Because of this tradition, she has a special love of butterflies and we have a special connection.

My grandkids look forward to

My grandkids look forward to this each year! We ordered 2 cups of caterpillars but last 2 years one of the cups only had 3 turn into chrysalis, the other cup produced 5. So they were a little disappointed that it happened again this year but still enjoyed the process! We had 8 beautiful painted ladies:)

This would be the 2nd

This would be the 2nd time I purchased 2 cups of caterpillars from you. This was just as amazing as the first time. This time we let the kids in my wife's school handle them and release them. They loved it. Thank you

The order was received in

The order was received in wonderful condition and there was plenty of communication so that I was prepared to receive the caterpillars. All of the larvae were healthy and grew into beautiful painted lady butterflies. Our preschoolers thoroughly enjoyed it!

Each cup only contained 4

Each cup only contained 4 caterpillars, not 5. However, all 8 caterpillars survived and hatched into the most beautiful painted ladies I’ve seen yet. We were able to keep them for 3 days before they started mating and we had to release them.
