New squash bug nymphs lack wings and have a green abdomen and red head, antenna, thorax, and legs. Over the following four to six weeks, they molt several times changing to a gray color with dark legs and antennae. Adults overwinter in field borders, wood piles or crop residues in the field. They have piercing mouth parts to suck the sap from leaves causing them to wilt and dry. Their feeding can also cause scarring on the fruit later in the season. At the Farm Hub, we monitor squash bug egg, nymph, and adult presence in the winter squash during the growing season. There were high numbers of eggs and nymphs this year, many nymphs hiding under the mulch in the field and scurrying away when we tried to get a closer look.&nbsp;&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/hvfarmhub.org\/wp-content\/uploads\/2022\/11\/Image4.jpg\" alt=\"\" class=\"wp-image-27721\" srcset=\"https:\/\/hvfarmhub.org\/wp-content\/uploads\/2022\/11\/Image4.jpg 1000w, https:\/\/hvfarmhub.org\/wp-content\/uploads\/2022\/11\/Image4-400x267.jpg 400w, https:\/\/hvfarmhub.org\/wp-content\/uploads\/2022\/11\/Image4-18x12.jpg 18w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><figcaption class=\"wp-element-caption\">Older nymphs under a leaf. They stay close together at the nymph stage but become more solitary as adults. <\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">The smooth and shiny eggs in the field were intriguing, so we brought them in to get a closer look under the microscope. We captured a few pictures of the eggs when suddenly they started hatching and young nymphs started to slowly emerge. The process for one egg to hatch, from the egg cracking open to the young squash bugs wobbling on top of other eggs, takes about five minutes to complete. One by one they emerged until most of the young squash bug nymphs were out, slowly trampling on top of each other. It is not every day one gets to see these bright colored critters, with such detail, start their life cycle. Watch below a time laps video of hatching squash bug eggs.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-vimeo wp-block-embed-vimeo wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/vimeo.com\/766159827\n<\/div><figcaption class=\"wp-element-caption\">A squash bug emerging from an egg.<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-vimeo wp-block-embed-vimeo wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/vimeo.com\/766160932\n<\/div><figcaption class=\"wp-element-caption\">Time laps video of a hatching squash bug egg. <\/figcaption><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">At high numbers, squash bugs can cause damage to crops. However, it is interesting to see them hatch up close.
